Abstract
A flanged parallel-plate waveguide is used for the detection of a two-dimensional surface crack on a metal plate. The Fourier transform and the mode-matching technique are used to obtain simultaneous equations, which are solved to represent the crack characteristic signal. The characteristics of the crack, such as position, Width, depth, and material in the crack, are discussed in terms of the crack characteristic signal
